We still don't know exactly how that is going to play out in the end. And we won't until we actually play the DLC. Remember what happened to the dark energy script?

Shep had his Dickshep moments in ME1 as well. They were just mostly lacking in ME2 unfortunately.
I got my perfect ending! Horus Shepard was dragged out of the wreckage of the Citadel's core and retired to Hawaii with Ashley Williams. When Garrus gets the chance to break away from his duties as Turian ambassador to the Quarians, Shep and Vakarian kick it on the beach toast to the memory of those lost, and knock back some brews. Head canon FTW.
On the matter of video games and choice, one of my American friends on the BSN just posted this little gem explaining the situation perfectly:
Tali is one of the two best girls (with liara) but if you dont romance (provided she survives) Tali she will hook up with Garrus.
But Liara will be forever alone as the shadow broker.
We can either have two happy people, or we can have 4 happy people.
You can now chill out at the beach with Garrus while you have both your LI's with you.
The beer suddenly tastes alot better.
